JUSTIN Bieber has blasted the media and professed his belief in God during another one of his Twitter rants.

The 19-year-old felt the need to defend himself following rumours that he’d been acting like a diva ahead of his concert at London’s o2 Arena this week.

Beginning his Twitter rant with a dig at the recent stories, Bieber wrote: “rumors rumors and more rumors. nothing more nothing less. might talk about them 1 day. rt now im just gonna be positive. cant bring me down.

“im focused on the good things in life. im blessed and not forgetting it. im giving back every day for it. cant phase me. fake stories to sell papers i guess are part of the job. but im a good person. i know that. u cant tell me different. we know the truth.”

Fans and their parents were left disgusted on Monday night after waiting, what they say, was two hours for the Canadian pop star to come onstage.

Young girls came forward to say that Bieber barely spoke to them for ten seconds after they won a competition to meet him backstage, while staff at the London venue claimed that he had acted like a diva before his concert.

Bieber addressed these claims as he continued to set the record straight with his followers.

“As long as my family, friends, and fans r with me u can say whatever. we are all equal in God's eyes & we have a responsibility to eachother, so make up stories about fake fines and make no mention of the positive....

“Or say when i came out of my show with my shirt off because after performing for 2 hours i might be sweaty i was going into a club (really?) or any girl i stand next to is my girl or that i dont care, or that i dont feel, or that a 19 year old going to a club in europe is wild.

“I understand it is part of the job to be judged...but judge me on the facts, judge me on the music, and be careful of the judgement u pass. but know this...im only judged by one power, and i serve him.

"So yeah I will continue being me. i will continue to serve, to perform, to care, to love, to smile, to dance, to play, to sing... and u are welcome to join, because i carry no hate. We got to much love for that. Im about the music.”

Finishing off his rant on a positive note, Bieber then headed out in the Capital to enjoy a night off before performing at the O2 Arena again this evening.

However, he did little to go unnoticed as he went for a meal at Chinese restaurant Mr. Chow in Knightsbridge.

Rather than keep a low profile, the singer sported a bizarre black rubber gas mask , which he teamed with a baseball cap and a hooded cardigan.

He is then thought to have headed back to his Park Lane hotel where he spent time watching movies with his entourage.
